The Portuguese house of stone

More and more people are trying to use eco-friendly and sustainable materials to build houses. A Casa do Penedo, or "the House of Stone", in the Fafe mountains in Portugal has become a real tourist attraction. The owner, Vitor Rodrigues has had to move out of this four-bedroomed house because of the tourists clamouring for a look inside. The remote location has led him to install bullet proof windows, a steel security door and a cement and eucalyptus tree sofa that weighs 350kg to discourage robbers.
